The cause of this is a broken back port of the upstream change set: https://github.com/memcached/memcached/commit/d9cd01ede97f4145af9781d448c62a3318952719
That changeset uses strncmp whereas the .diff file uses strcmp ++ if (ptr - c->rcurr > 100 || ++ strcmp(ptr, "get ") && strcmp(ptr, "gets ")) { ++ conn_set_state(c, conn_closing); ++ return 1; ++ } Given that the string being compared contains either "get HUGE KEY" or "gets HUGE KEYS" the check in the ubuntu diff will *always* return false. Simply correcting that back port appears to solve the problem for us. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/637114 Title: Large multiget requests randomly broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/memcached/+bug/637114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
